[QUOTE="Pascal95, post: 100915, member: 18962"] [SIZE=4][FONT=arial]Hi from France I acquired my spark (with OTG cable – Samsung Galaxy S7) since early 2019. I did some flights without any problem, thanks to you and your advices. But on holiday in Iceland, a wonderful country, last august, I almost lost my spark several times. Magnetic field interference, compass error, yaw error. I have to calibrate compass when I arrived in Iceland (but not IMU) First flight, apparently no problem (but a few compass errors I saw later in the log) Second day : compass errors and ATTI mode (first time for me) and panic because of speed, but I managed to get it back. It was careless but I tried several times that day because I really wanted to film but, each time, there were errors. I tried to calibrate compass the next day but with the same problems. I finally stopped using Spark because I was too scared to lose it definitively. Back in France, I have not used Spark yet (maybe also a little stressed) Do you think I should have calibrate IMU too ? Do you think my spark has another problem ? I have read somewhere that magnetic fields in Iceland are weak and might cause errors. Thanks for your advices. You will find below some links of my flights.[/FONT][/SIZE] [URL unfurl="true"]https://www.phantomhelp.com/logviewer/2SRTZLZFX4LJXBK5J08X[/URL] [URL unfurl="true"]https://www.phantomhelp.com/logviewer/M158JUDUHDZYIKXL39MC[/URL] [URL unfurl="true"]https://www.phantomhelp.com/logviewer/PORVLHZGKZKLK7J75W8Z[/URL] [/QUOTE]
